To alt whom may concern;

lie it known that 1, Jumps DORNWPH, a subject of the German Emperor, andresiding at Berlin, Germany, have invented cer tain new and usefulImprovements in Matrix-Line Setting and (lasting llilachines, of whichthe following is a specification.

ln matrix-line setting and casting inachines having matrices guided onwires, the line, after it is cast, is freed from the bur adheringto itat the upper portion carrying the characters, by passing between two.adjustable knives. The holder carrying the knives, is secured to a slideblock which is arranged near the casting point coinciding X with thesetting point. At this point however there are arrtnged in a verylimited space, various other parts, so that this part of the machine isnot easily accessible for thevarious manipulations which have tobeeffected. When the line is cast, the casting mold holder with thefinished line and the casting pot are moved to their originalpd sition.Before however the casting mold holder reaches its initial position, theslide block carrying the knifeholder passes over the partly ejected linestill contained in the lasting mold, in order to remove the bur adheringto it. The opening of the casting pot filled with liquid, lead, is, inthe advanced position. of theslide block, exactly above it, that thecompositor, when Loosening the a screw by means of which the knifeholder is f secured to the slide block, is liable to in ure himself bycontact with the hot casting pot.

Another disadvantage is that thismethod of securing is very tedious andlei'igthy.

'.l;he invention is intended toobviate these and to enable the knlle theknife holder is not firmly screwed to the slide block as hitherto, butis loosely mounted in a slot or a guide of the slide block and heldtherein by an easily folding bracket which. is pivotally mounted on theslide block. p

A construction according to this invention is illustrated in theaccompanying drawing in which, i

I claim herein as my invention:

1. In apparatus for triinn'iingftype lines 1 in matrix line so log andcasting machines,

the combination or two knives located one on each. side of: the typeline to be trimmed, a holder for said knives, means to reciprocate saidholder, and a detachable device to connect the holder to thereciprocating means.

2. ln apparatus for trimming type lines on cachiside oi. the type lineto be trimmed,

a holder for said knives, a rod to carry said holder, a hook pivoted tosaid rod, a promy name in the presence of two subscribing jection on theholder adapted to detaohably Witnesses. engage the hook means toreciprocate said JULIUS DORNETH. rod, ande locking pin in the hook forthe v 5 purpose set forth.

In Witness whereof, Ihave hereunto signed \Vitnesses WVOLDEMAR I-Lxmrr,HENRY HAsPER.
